CCV :Continuing Calibration Verification-Analyzed to verify the instrument calibration is within criteria. CCB :Continuing Calibration Blank-Analyzed to verify the instrument baseline is within criteria. Blank :Method Blank-Prepared to verify that the preparation process is not contributing contamination to the samples. ExBlk :TCLP/STLC Extraction Blank-Prepared to verify that the preparation process is not contributing contamination to the samples. LCS :Laboratory Control Standard/Sample-Prepared to verify that the preparation process is not affecting analyte recovery. MS Matrix Spikes-A random sample is spiked with a known amount of analyte.The recoveries are an indication of how that sample matrix affects analyte recovery. MSD :Matrix Spike Duplicate of MS/MSD pair-A random sample duplicate is spiked with a known amount of analyted.The recoveries are an indication of how that sample matrix affects analyte recovery. MSRPD :MS/MSD Relative Percent Difference(RPD)-The MS relative percent difference is an indication of precision for the preparation and analysis. ND :Non-detect-Result was below the DQO listed for the analyte. <y4 :High Sample Background-Spike concentration was less than one forth of the sample concentration. DQO :Data Quality Objective-This is the criteria against which the quality control data is compared. Explanation 220 :The CCB was greater than the DQO.However,all results were either five times greater than the CCB concentration or ND relative to the PQL. 430 :Post Digestion Spike(PDS)not within Acceptance Range(AR)because of matrix interferences affecting this analyte.Data was accepted based on the LCS recovery. 435 :Sample matrix may be affecting this analyte.Data was accepted based on the LCS or CCV recovery.
